Improvement in ore-washers



UNITED STATES PATENT OEEIGE DANIEL ZEIGLER, OF LEVVISTOWN, PENNSYLVANIA.

IMPROVEMENT IN ORE-WASHERS.

Specification forming part of Letters Patent No. 147,464, dated February 10,1874; application led September 8, 1873.

To all whom it may concern Be it known that I, DANIEL ZEIGLER, of Lewistown, in the county of Mifflin and in the State of Pennsylvania, have invented certain new and useful Improvements in Ore and Sand Washers and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specifi` cation.

The nature of my invention consists in the combination of a wash-box and an oscillating or swinging rake and stirrer, for washing ore or sand, and such articles, as will be hereinafter described.

In the annexed drawings, which is a perspective view, and which forms a part of this specification, A represents a rectangular box, which may be made of any suitable size, but two or three times as long as it is wide. One end of the box is provided with a doorway, G. B B represent cross-bars, which connect and are secured upon the end posts of the frame holding` the box A. I?ivoted to and depending from these bars are two swing bars or rods, C G, which are hinged at their lower ends to a rake and stirrer, D. This rake consists of a long iron plate, or slab of wood or iron, provided on its under side with rows of teeth, which have their front edges straight and their rear edges curved, as seen at a e.

This stirrer oscillates or swings backward and forward longitudinally of the box.

Then ore or sand is placed in the box, and the stirrer is set in motion, it will be seen from its motion and formation that it has a tendency in its forward motion to carry the material in the box constantly toward the doorway G, and that, as it returns or moves backward, it lifts, and its teeth, by their beveled backs, pass over the material.

The reason of the lifting of the stirrer as it passes backward results from the fact that its furthermost forward motion is not beyond a perpendicular of the swing-bars C C.

This stirrer is worked by power, and not only thoroughly stirs the material within the box, butrakes out the heavy particles of stone or other matter which it is desirable to move.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The box A, with its doorway G, in combination with the swinging stirrer D, constructed with its teeth e c, and operated as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this ..7th day of August, 1873.

DANIEL ZEIGLER.
